I'm running 3.9.2285~gc6793b3. I built it myself so that I could enable transcoding. The following are all of the commands I used.
apt-get install build-essential pkg-config libssl-dev git
(Not entirely sure this was necessary)
apt-get install libavahi-client-dev libavcodec-dev libavfilter-dev libavformat-dev libavutil-dev libswscale-dev libavcodec-extra-53 liburiparser1 liburiparser-dev debhelper libcurl4-gnutls-dev a52dec
git clone https://github.com/tvheadend/tvheadend.git
apt-get install debhelper
apt-get install libavahi-client-dev
apt-get install libcurl4-gnutls-dev
apt-get install liburiparser-dev
AUTOBUILD_CONFIGURE_EXTRA=--enable-libffmpeg_static ./Autobuild.sh -t precise-amd64
dpkg –i PACKAGENAME
I haven't set up any stream filters but I did add a couple custom stream pofiles... This wouldn't effect anything would it? I was originally trying to record to a network share and I got the same error. I can't remember for sure, but I think I tested recording right after I configured all of my channels and I thought it worked? Maybe changing the record directory to a mounted network drive messed something up? The network drive was mounted in /media as /media/recordings/. The permissions on the network share are configured to allow read and write access to any user and the /home/hts/ folder is default. I changed the recordings directory to /home/hts/ because I thought it was the defualt.
I turned on debug and when I record I get another error but it seems unrelated...
